The second victim named on Saturday was Terry Andres, 62, who worked at the Norfolk naval shipyard in Virginia. He was going on holiday with his wife, who was unharmed.

New Jersey-born Esteban Santiago, 26, was charged on Saturday night by the FBI over Friday’s rampage, in which he shot 13 people seemingly at random – five of whom died.

The charged could bring the death penalty, if he is convicted.

He is charged with an act of violence at an international airport resulting in death. The punishment is execution or any prison sentence up to life. Prosecutors also charged Santiago with two firearms offences.

It emerged that police in Alaska took a handgun from Santiago, , but returned it to him last month after a medical evaluation found he was not mentally ill.

The FBI said on Saturday that they had not ruled out the possibility of terrorist links, and believed he had planned the attack. The New York Times reported that he had viewed extremist material online.

“Indications are that he came here to carry out this horrific attack,” said George Piro, special agent in charge of the Miami division of the FBI. He also said that, contrary to initial reports, he had not found any evidence of an “altercation” on the plane that may have sparked the violence.

“We have not identified any triggers that would have prompted him. But it’s still early in the investigation,” he said.

“We have interviewed all of his family that we have identified so far. We are looking at his social media, it’s giving us a picture of the individual, but it’s too early to rule out anything, including terrorism.”

Santiago is now known to have arrived in Florida from Alaska, legally transporting a 9mm semi-automatic hand gun in his luggage, which he declared to the airline – following correct procedures.

The unloaded gun must be placed inside a locked, hard-sided case inside the suitcase. Small arms ammunition, including ammunition not exceeding .75 caliber and shotgun shells of any gauge, may be carried in the same hard-sided case as the firearm.

Americans will be deeply reluctant to increase restrictions on transporting guns in checked baggage, given the number of guns which are transported for hunting and target shooting.

Santiago, a former member of the National Guard, who was presented with a medal for his service in Iraq from 2010-11, had a concealed-carry permit. And as a military veteran he would easily have passed a background check – especially in Alaska, where he lived, which is a famed shooting, gun-loving state.

Yet questions are now being raised as to how he was allowed to retain his weapon, despite going to the FBI and “exhibiting signs of mental illness,” according to Mr Piro.

In November, two months after he had become a father for the first time, Santiago went to the FBI in Anchorage and said he was hearing voices, which told him to join Isil. He reportedly believed the CIA were involved.

“It is very normal for citizens to walk into field offices,” said Mr Piro, speaking outside Fort Lauderdale airport on Saturday.

“Our offices are open to the public, and we welcome them coming in to provide assistance. It was during that contact that the agents themselves noted the erratic behaviour, and pushed them to call the authorities and take him for mental evaluation.”

Karen Loeffler, US attorney for the district of Alaska, said that there was no legal requirement to take Santiago's gun away from him. To do so, she said, he would have to have been "adjudicated mentally ill."

"This is not somebody who would have been prohibited, based on the laws we have," she added.

The FBI in Alaska said they believed his November 2016 arrival at the FBI offices was a mental health issue, not a terrorism one.

But police were aware of him, having been called to his home on domestic violence charges, having attempted to strangle his girlfriend. He was due to appear in court later this year.

His aunt, who lives in New Jersey, and brother, who lives in Puerto Rico, said that they believed he was hallucinating, and that he had spent a fortnight in a mental health facility.

Asked whether the FBI should have intervened and rescinded Santiago’s gun licence, Mr Piro said: “I’m not in a position to answer that. It’s too early.”

Six people remained in hospital; three of them recovering well, and three in intensive care.

“I have a brother who suffers with mental illness,” he said. “It’s very hard to deal with these issues. Every family struggles with this.

“After we know more, we’ll be able to discuss this.

“We’re going to have a conversation about how to live in a safe society. We all want to live in a safe society. I’ve got kids, I’ve got grandkids – we want to be safe. We have to find out what happened, then try to make it better.”

Last year broke all records for gun sales in the US, with 27 million firearms purchased in 2016 – partly in response to fears that Hillary Clinton, if elected, would clamp down on weapon sales.

And the shooting came as Florida was preparing to consider legislation that relaxed its gun laws, and eliminate “gun-free zones” in airport terminals, schools and government buildings.

On television networks pundits were arguing that having more armed people in the vicinity of Fort Lauderdale airport would have saved lives - despite the sheriff confirming on Saturday that between Santiago firing the first shot and being arrested, a total of 80 seconds elapsed.
